Just under one in five U.S. adults, 18%, can be described as vaccine-resistant. These Americans say they would not agree to be vaccinated if a COVID-19 vaccine were available to them right now at no cost and that they are unlikely to change their mind about it. The percentage holding these views has been stable in recent months.

Another 5% of Americans would not agree to be vaccinated but say they are at least somewhat likely to change their mind.

The remainder of U.S. adults either report having already been vaccinated (69%) or say they plan to be (8%). The vaccinated group is up from 64% in May but shows little change from the 68% recorded in June.
